Y ward pressure the matrix is pulled up enough to clear the raised type formed on the sheet by the friction of the centering pin, and any suitable spring action (not shown) brings the matrix bar back to its original position.

The method and means of injecting the type metal is the same as in monotype machines and consists in general of an upwardly projecting nozzle 32 which receives molten metal from a melting pot 32 and a sm l pu (not shown) which pumps the molten metal upwardly through the nozzle 'and 'af hole 33 in plate 7, through the previouslydescribed slot" 31 in the sheet at ,theinstant the matrix is in place. Usually this process leaves some surplus metal sticking to the .under side of the sheet when it cools, but this metal is instantly sheared off by any-suitable device or means such as ai shifting movement of plate 7 caused by thecompression lever 19 which, on its back stroke, contacts with the lower arm of a rocking lever 34 pivoted at 35 and-having its upper. arm connected to the rear end of arm of plate 7; A small compression coil spring36 onsaid arm and interposed between lug la -and a fixed collar I machines (not shown), 40

plate when. the removal of surplus metal takes place, by means common to monotype allowing said metal to drop back into the pot 32 The means for punching the slits 31 in I centering I down parallel thereto far enough to punch the type sheet consist simply of a vertically arranged punching bar 38 secured to the pin (see 3) and extending a slot in the type sheet at the same time the centering pin is holding a matrix down in place. Thus when the sheet is automatiject molten metal therethrough. It will be readily seen that during the process of making each letter the slot 31 is also filled with metal which .is allowed to remain there, but the surplusmetal on the lower side of the sheet is sheared off as described.

In Fig. 4 I have illustrated the upper right hand portion of a type sheet on which a line of raised type has been started, it being understood that the lines of type being at the right, the type sheet being shifted toward the right for each successive letter and a slot 31 is always found to th left of the last letter for the purpose previously described.

It is readily understood that with my process of. making raised letters integral with a sheet, both of type metal, any size of typed sheet can be made and such sheet is readily bent to fit the curved surface of a printing cylinder and attached to any part of such cylinder, or such sheet may be left flat and mounted on a block as "a cut for printing purposes.

vMiy device practically eliminates the use of the presentmonotype machines and effects an enormous saving in the amount of type metal used.

What I claim is:

The method of making type for printing purposes which raised letters of type metal on the surface of a sheet of similar metal, said letters each formed of molten type metal injected'from the under side of the sheet through a punched slot in the latter and into a mold formed by a matrix resting'on the top surface of the sheet, said injected, molten, letter-forming metal adapted to become permanently associated with the said sheet when the metal cools.

In testimony whereof I afiix my signature.
